What parts does a plant have? Let's find out! 1.7.2013 Before we start, let's look at these lovely pictures. Can you tell me what they are? Yes, they are all plants!

Let's learn together! ‹#› Parts of a Plant (1) 1. seed /siːd/ (种子) The beginning of a new plant. 2. root /ruːt/ (根) Helps the plant stand and take in water. 3. stem /stem/ (茎) Holds the plant up above the ground. 1.7.2013 This is a picture of a plant. Let's learn its parts. First, this is the 'seed', it's the beginning of a new plant. Under the ground, we have the 'root', it helps the plant stand and take in water. Above the ground is the 'stem', it holds the plant up. ‹#› Parts of a Plant (2) 4. leaf (叶子) Pronunciation: /liːf/ (Plural: leaves) Function: They make food for the plant. 5. flower (花) Pronunciation: /ˈflaʊə(r)/ Function: The beautiful part. Some flowers become fruits. 1.7.2013 Great! Now let's look at the parts above the stem. These are the 'leaves'. They make food for the plant. And this beautiful part is the 'flower'. Some flowers will become fruits. Remember, the plural of 'leaf' is 'leaves'. ‹#› Let's Match! 1. seed 2. root 3. stem 4. leaf 5. flower 💡 Point to the part and say the word. 1.7.2013 Now it's time for a game!

Work with your partner and say the words aloud. ‹#› Look and Learn Key Dialogue & Patterns A:What are you doing? B:We're digging. Grammar Focus: Question: What are you doing? Answer: We're + V-ing (doing) 1.7.2013 Look at Lingling and Daming. What are they doing? They are digging in the garden. So when we want to ask someone what they are doing now, we can say "What are you doing?". And the answer is "We're digging." or "I'm ...". ‹#› Sam's Seeds (Part 1) "We're making a small garden for the class!" Amy: "I've got tomato seeds." Daming: "I've got bean seeds." 1.7.2013 Today's story is about Sam and his friends. They want to make a small garden for their class. Everyone has brought different seeds.
